Application filed my -1, 1923, Serial No. 635,912. Renewed October 22, 1924..

Be it known that I, HENRI Ban'rz', acitizen of the United States, residing at St;

Louis, State of Missouri, have invented certain new and useful Improvements in Air Heaters, of which the-following is a specification.

' 'heightsfrom the floor able baflies in the air discharge.

.my improved 'air heater with parts My invention has relation to improvements in air heaters and .the method of mounting them, and consists in the novel features of construction more fully set forth in the specification and pointed out in the claims.

The object of the invention is to provide an air heater for foun' ries or rolling mills or other buildings-wherein the entire floor space is utilized and cannot accommodate t e heating apparatus. In heating buildings of this kind I provide an air heater that may be mounted-upon the pillars supporting the crane rails or the roof. In or der to have the hot air discharged from the heater in planes that will pemit it to be immediately' available to the workmen, I invert the heater, that is, arrange it so that the cold air will be taken into the heater at the to and'the heated air will be discharged P at'tlie bottom. I find this desirable since it enables the heaters to be mounted a considerable distance above the 'floor.. Further'objects are to provide an air heater in which the air intake may be adjusted to iiferent and to provide movpipe so that the heated air maybe 'directed up or down as desired; Further advantages will be apparent from a detailed description of the invention in connection with the accompanyingfdrawings, in which-- igure 1 is more' or less an outline view of a building to be heated with my improved heater mounted on .a pillar some distance above the floor Fig. 2 is a side elevation of away to more clearly show the invention; Fig. 3.is of 90 from Fig. 2, parts bein broken away; Fig. 4 is an enlarged view the end of one of the hot airoutlet pi es showing "the" arrangement for moving t e baflies' in saidpipe; Fig. 5 isa cross-sectional view taken on the line 55 of Fig. 4.

- Referring. tothe B represents thebuildingto be'heated w erein there is a broken a side elevation looking at an angle crane C adapted to travel on the track T supported by pillars P, P,. etc. The build,-

mg s heated by my improved air heater H mounted ona pillar P, it bein understood heater casing 2. The 0 ening O on the sideof the casing adjacent t e pillar P commumcates with a vertically dis osed air intake pipe 3, while the opening on the opposite side of the casing communicates with the top section .4 of a series of telescopic pipe sections 4, 5, and 6, the object of WhlOh is to enable these'sections to be collapsed for the purpose of enlarging the floor space about the heater when this is necessary.

scoped within section 4 for the purpose of furnishing the openin O with warmer air when it is desired. 7ithin the casing 2 between the openings 0, O a multi-vaned fan 7 is mounted on a shaft 8 supported in bearings 9, 9 within the pipes 3 and 4, the shaft 9 also carryin a pulley 10 at one end, over which is passed a belt 11, said belt also passing over pulley 12 of a small motor13 restin on a platform 14 secured to casin 2.

Wit the casing 2 and below the mu tivaned fan 7 "is a bank of steam coils 15 having an inlet 16 and an outlet 17. The casing 2 terminates at its lower end in a pair of rectangular discharge pipes 18, each of which desiredpfThe dampers 19, 19 are held in theiradjusted passing throng lever arni 22 'of one of the dampers 19, said pinbein inseft'a'ble in any one of a series of holes 23 in a quadrant 24 secured tothe side of each pipe 18. The outer reduced portion 21' of pin 21 has a said'spring maintaining the osition b means of a pin 21 in in the quadrant hole 23 to hold the ampere against,

movement. v

In operation of my heater the cold an At the same time the sections. 5 and 6 may be teleone en of link and the spring coiled about it,

as is neoesis drawn into the casing 2 through pipe 3 and telescopic pipes 4, 5, and 6 by the fan 7 and is then forced downwardly through the casing over the bank of steam coils 15 and out through the pipes 18.

Having described my invention, I claim: 1. In an air heater having an air intake opening at the top and an air discharge opening at the bottom, a telescopic intake pipeconnected with the intake opening, an outlet pipe connected with the outlet open ing, a heating element between the intake and the outlet openings, said outlet pipe having a plurality of air deflectors, said deflectors being connected on the outside of the pipe, and means for locking said deflectors HENRY BAETZ.
